The objective of this research was to develop a stem height measurement system forMiscanthus giganteus (MxG), to be used as a component in a future Look Ahead Yield Monitor (LAYM). For this purpose, a SICK LMS 291 LIght Detecti...

Weeds are regarded as farmers' natural enemy. In order to avoid excessive pesticide residues, the destruction of ecological environment, and to guarantee the quality and safety of agricultural products, it is urgent to develop highly-efficient weed management methods. Amongst, weed discrimination is the key part. There have been a lot of researches on weed detection/discrimination using spectra...

Tomato crop is primarily infected by various common diseases like Bacterial Canker, bird's-eye fruit spots, Bacterial Spot, Chlorosis, Curly Top, Early Blight, Fusarium Wilt, Gray Leaf, Gray Mold Rot, Leaf Mold, Leaf Roll and Leaf Curl, Powdery mildew, Septoria Leaf Spot, Tobacco Mosaic Virus, Verticillium Wilt. The presented work describes a algorithm for different disease detection based on t...

Evaluation of the MODIS Crop Detection Algorithm (MCDA) procedure for estimating historical planted soybean crop areas was done on fields in Mato Grosso State, Brazil. MCDA is based on temporal profiles of EVI (Enhanced Vegetation Index) derived from satellite data of the MODIS (Moderate Resolution Imaging Spectroradiometer) imager, and was previously developed for soybean area estimation in Ri...

In a rapidly changing landscape highly impacted by anthropogenic activities, the great apes are facing new challenges to coexist with humans. For chimpanzee communities inhabiting encroached territories, not bordered by rival conspecifics but by human agricultural fields, such boundaries are risky areas. To investigate the hypothesis that they use specific strategies for incursions out of the f...

The CRISPR/Cas9 system is rapidly becoming the reagent of choice for targeted mutagenesis and gene editing in crop species. There are currently intense research efforts in the crop sciences to identify efficient CRISPR/Cas9 platforms to carry out targeted mutagenesis and gene editing projects. These efforts typically result in the incremental tweaking of various platform components including th...

India is one of the largest cotton-growing countries. Cotton is a fiber crop with varied applications from making tiny threads to fashionable clothing in the textile sector. In the near future, cotton crop will gain popularity as a multipurpose crop in India. The commercialization of Bt cotton in 2002 and consequently the fast adoption of Bt cotton hybrids by cotton farmers have enhanced the co...

The situation of cropland use in China is very complicated. In many areas, the cropland is used in multi-cropped ways. There is a need for better information on the area and distribution of cropland using in different cropping rotation systems, but it is not easy to get it in traditional census ways. This paper focuses on the methodology of crop rotations detection in China using multitemporal ...

In a vision-based automatic agricultural vehicle guidance system for row-crop applications, finding guidance information from crop row structure is the key in achieving accurate control of the vehicle. This paper describes a robust procedure to obtain a guidance directrix. The procedure includes row segmentation by K-means clustering algorithm, row detection by a moment algorithm, and guidance ...

Several studies in the past have examined the spectral capability of multispectral and hyperspectral imagery for the identification of crop marks, while recent studies have applied different vegetation indices in order to support remote sensing archaeological applications. However, the use of vegetation indices for the detection of crop marks lacks in accuracy assessment and critical evaluation...
